P0311

DTC P0311, sometimes indicated as P031100 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the ignition system causing cylinder 11 misfire detected.

A misfire occurs when an engine does not ignite the air/fuel mixture in the combustion chamber properly. This can cause significant problems, including decreased fuel economy, poor performance, and even engine damage.
There are many potential causes of cylinder misfires, including bad spark plugs, worn piston rings, or a clogged or dirty fuel injector. The most common cause, however, is a bad ignition coil.
If your car is experiencing a misfire, the best solution is to have a qualified mechanic diagnose the problem and fix it. However, there are some things you can do to help troubleshoot the issue:
-Check the spark plugs and replace them if they are worn or damaged.
-Check the fuel injectors and clean them if they are dirty.
-Check the ignition coils and replace them if they are bad.
-Check the compression of each cylinder and repair any problems that are found.
